PNEUMATIC STRAW-STACKER.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed May 18, 1906- Serial No. 317,640.

To all whom, it may concern.-

it known that I, TnAvEs N. SELLERS, a subject of the King of GreatBritain, residing at Munro, in the county of Perth, Province of Ontario,Canada, have invented certain new and useful Improvements in PneumaticStraw-Stackers, of which the following is a specification.

My invention consists in improvements in pneumatic straw stackers, andrelates more particularly to means for laterally swinging the dischargechute thereof, which I accomplish by Simple and efficient mechanism bywhich such stacker chute is readily swung from side to side, orcompletely revolved, and positively held at any desired point so thatdisplacement thereof by action of the wind or otherwise is prevented. Inthe accompanying drawings, which are made a part hereof, and in whichsimilar reference characters indicate similar parts, Figure 1 is acentral vertical sectional view of that portion of a stacker to which myinvention is applicable, as seen from the dotted line 1.-1 in Fig. 2;Fig. 2 is a horizontal cross section on the dotted line 22 in Fig. 1.Fig. 3 a rear elevation of the structure; and Fig. 4., a fragmentarydetail view in cross section on a somewhat enlarged scale showing theconnection between the internal gear ring and associated parts, as seenfrom the dotted line 4i l in Fig. 2.

This stacker revolving mechanism is preferably composed of an annularbase plate 5 suitably secured to the stacker frame or separator, uponwhich plate is mounted an internal gear ring 6 by means of pins 7 orotherwise. Between flanges 8 and 9 of said plate and gear ring,respectively, is secured the flanged lower end 10 of the collar 11 whichsurrounds the stacker chute 12. I may also interpose ball or otherantifriction bearings between these engaging members in any desirablemanner, the preferred construction being ball bearings, as 13, shown inFig. 1.

I. provide supporting arms 15 (Fig. 2) on either side of the stackerchute, which are preferably integrally formed with, or secured to, thecollar 11, to which. arms the yoke 16 is pivotally secured by the rod 17or in any other suitable manner, this form of yoke and arms being acommon constructlon for supporting stacker chutes. Arms 18 are bolted tocollar 11 upon which arms I mount a frame consisting of the standards 20between the lower ends of which is a shaft-bearing 21 which isintegrally formed with said arms 18. As will be readily understood,collar 11, arms 15 and 18, and shaft-bearing 21, may be formedintegrally, in which case the employment of bolts or other securingmeans is unnecessary. Above said bearing 1. place connecting bar 23provided with a bearing 24, said bar 23 being provided with an arm 25betweenwhich arm and one of the standards is mounted a shaft 26 bearinga worm gear L7, to which shaft a crank 28 is attached. 1 may alsoprovide braces 29 connecting the collar and standards, thus insuring aperfectly rigid structure.

A shaft 30 is mounted in bearings 21. and 24, the upper end of saidShaft being provided with a pinion 31 which engages with worm gear 27,and has a pinion 32 also at its lower end which. engages with theinternal gear ring 6. Near the upper ends of standards 20 is secured ashaft 33 upon which is mounted a drum 34:, said shaft being providedwith a pinion 35 which engages with a crank-operated worm-wheel by theturning of which crank 28 the cable 37 is wound or unwound to raise orlower the stacker chute.

To prevent chaff and dust from entering the turn-table I provide theplate 38 (indicated by broken lines, Fig. 2) which is suitably securedto collar 11 or otherwise and which coveis the gear ringfi, said covermoving around with the chute when revolved.

In operation, when it is desired to swing the stacker chute from side toside, or com.- pletcly revolve it, crank 28 is turned, causing worm 27and pinion 31 to impart rotary motion to shaft 30 and pinion 32, whichlatter pinion, engaging with internal gear ring 6 is caused to travelabout said ring, thereby carrying with it the stacker chute and partsconnected therewith, the worm and pinion insuring that the revolution ofthe stacker chutewill cease at any pointupon the discontinuance of themanipulation of the crank, in which position it will remain without theemployment of any other retaining means. It will be apparent, therefore,that the operator has unobstructed control of the com plete revolutionof the stacker chute, there being no projecting or adjacent mechanism inthe path of travel of the chute, which is an objection common to variousconstructions of stackers by reason of cranks, hand-wheels, pulleys andthe like, for operating the turntables, being permanently located insuch positions as to be crossed by the stacker chute while revolving,thereby interfering with the convenient operation of such mechanisms bythe operator; while with my device the revolving structure has a clearand uninterrupted path of travel, as well as being a simple andeflicient device for the purpose, and one which insures positiverevolution of the chute without lost motion or liability of becomingimpaired.

I claim as my invention:

1. In a pneumatic stacker, the combination with the discharge chute, ofa collar, a gear ring engaging said collar, a closure for said gearring, driving mechanism engaging said gear ring, and means for drivingsaid mechanism.

2. In a pneumatic stacker, the combination, with the discharge chute, ofdriving mechanism composed of a gear ring, a framework, a shaftsupporting member in said framework, a shaft, a pinion on the lower endof said shaft, a pinion at the upper end of said shaft, and a worm gearengaging said upper pinion.

3. A revolving mechanism for stackers composed of a gear ring, a collarprovided with supports and a shaft bearing, standards having a shaftbearing therebetween mounted on said supports, a shaft mounted in saidbearings having pinions at its lower and upper ends which engagerespectively with said internal gear ring and a worm gear, and means foroperating said worm gear.

4-. A revolving mechanism for stackers 1 consisting of a base-plate, aninternal gearring mounted thereon, a collar revolubly mountedtherebetween, a closure for said internal gear-ring, and drivingmechanism connected to said collar and engaging said gearring whichmechanism when "operated revolves with said collar within said internalgear ring.

5. A revolving mechanism for pneumatic stacker chutes comprising abase-plate provided with an upwardly extending flange, a gear-ringmounted thereon having an inwardly extending flange, means for rigidlyconnecting said base-plate and said gearring, a flanged collar seatedbetween said base-plate and said gearring, a closure connected to saidcollar and covering said gear ring, driving mechanism connected to saidcollar and engaging said gearring, and means for driving said mechanismwhereby said collar with said mechanism is revolved. 6. The combination,with a discharge chute, of a collar surrounding said chute, an internalgear-ring engaging said collar, a clo-' sure connected to said collarand covering said internal gear-ring, supports and a shaftbearing onsaid collar, standards mounted on said supports, a cross-member betweensaid standards provided with a shaft bearing, a shaft supported betweensaid bearings, a pinion on the lower end of said shaft and engaging saidgear-ring, and means for driving said shaft, whereby said dischargechute with its driving mechanism is revolved about said internalgear-ring.
